       4 . The hydrostatic apparatus of  claim 2 , further comprising: 
 a charge pump having a housing attached to the end cap;    wherein the bracket is attached to the charge pump housing.    
   
   
       5 . The hydrostatic apparatus of  claim 2 , wherein the fan shroud further comprises a plurality of snaps that engage the bracket.  
   
   
       6 . The hydrostatic apparatus of  claim 1 , wherein the fan shroud engages the end cap.  
   
   
       7 . The hydrostatic apparatus of  claim 1 , wherein an input from a prime mover is attached to an end of the input shaft opposite the one end to which the fan is attached.  
   
   
       8 . A pump comprising: 
 a housing;    an end cap;    a charge pump mounted on the end cap;    a first end;    a second end;    an input shaft extending from the first end and the second end of the pump;    a fan attached to one end of the input shaft; and    a fan shroud attached to the pump, the fan shroud being positioned to generally enclose the fan.    
   
   
       9 . The pump of  claim 8 , further comprising a bracket to which the fan shroud is attached.  
   
   
       10 . The pump of  claim 8 , further comprising: 
 a plurality of first fasteners attaching the end cap to the housing;    a plurality of second fasteners attaching the charge pump to the end cap; and    a bracket attached to the pump by at least one of the first fasteners and the second fasteners;    wherein the fan shroud is mounted on the bracket.    
   
   
       11 . The pump of  claim 10 , wherein the fan shroud comprises a plurality of snaps, and the snaps interface with a feature on the bracket to secure the fan shroud.  
   
   
       12 . The pump of  claim 11 , wherein the fan shroud comprises a stop to position the fan shroud relative to the bracket.  
   
   
       13 . The pump of  claim 8 , further comprising: 
 a plurality of fasteners attaching the end cap to the housing;    wherein at least one of the fasteners attaches the fan shroud to the end cap.    
   
   
       14 . The pump of  claim 8 , wherein the fan shroud is attached to the end cap by a plurality of snaps.  
   
   
       15 . The pump of  claim 14 , further comprising: 
 a plurality of fasteners attaching the end cap to the housing;    wherein the fan shroud comprises a plurality of locating features that work with the plurality of fasteners to aid in maintaining the position of the fan shroud.    
   
   
       16 . A fan shroud apparatus for use in a hydrostatic apparatus comprising: 
 a bracket; and    a fan shroud comprising at least one fastener, the fan shroud being attached to the bracket;    wherein the bracket engages an end of a hydrostatic pump to allow the fan shroud to generally enclose a fan attached to the end of the hydrostatic pump.    
   
   
       17 . The fan shroud apparatus of  claim 16 , further comprising means for establishing the position of the fan shroud relative to the bracket.  
   
   
       18 . The fan shroud apparatus of  claim 17 , further comprising plugs on the fan shroud.  
   
   
       19 . The fan shroud apparatus of  claim 17 , wherein the fan shroud includes a skirt portion.  
   
   
       20 . The fan shroud apparatus of  claim 19 , further comprising plugs on the fan shroud.
